BACKGROUND OF THE INVENTION

1. Field of the Invention

This invention generally relates to a decorative member. More specifically, the present invention relates to a decorative member for outdoor use that has a surface that is externally exposed and adapted to be used outdoors.

2. Background Information

A decorative member for outdoor use such as a reel unit of a fishing reel or a counter case for a water depth display has a surface that is externally exposed. Such decorative member is provided, on the interior, with concave or convex portions such as installation bosses or bearing support members. For example, in a dual bearing reel, a boss for installing a coil spring on the interior of the side cover of the reel body, a threaded installation boss are disposed such that they project inward.

In the conventional art, decorative members are often manufactured by resin injection molding or by aluminum die-casting because these types of concave or convex portions are needed. When performing aluminum die-casting, a substantial amount of silicon is often added to the aluminum alloy in order to improve fluidity. Because of this, the decorative member will take on a whitish color, and a high quality appearance will be difficult to obtain even after an alumite treatment has been performed thereon.

Thus, finishing process such as plating or painting is performed on members that are formed from resin or by aluminum die-casting, so that a high quality metal-like finish can be obtained. However, these methods cannot produce a metal-like finish having a high quality luster. Instead, these methods will produce a finish that appears cheap.

Accordingly, forged or press molded members are used in high quality products in order to provide an expensive metal-like finish. Because it is not necessary to improve fluidity, forged members are provided with a high quality finish by using a surface treatment such as an alumite treatment or the like. Likewise, press molded members are provided with a high quality finish with the same type of surface treatment.

With conventional decorative members in which forged members are used, a plurality of post-manufacturing processes must be performed in order to form the concave or convex portions, which further increases the costs. In addition, with conventional decorative members in which press molded members are used, attachment portions such as screw holes and rivet holes for installing the concave or convex portions are exposed in the surface thereof, which creates problems with the aesthetic appearance of the product.

In view of the above, there exists a need for a decorative member which overcomes the above mentioned problems in the prior art. This invention addresses this need in the prior art as well as other needs, which will become apparent to those skilled in the art from this disclosure.

SUMMARY OF THE INVENTION

Purposes of the present invention are to prevent an increase in the cost of decorative members for outdoor use, to prevent the exposure of attachment portions in the surface of the decorative member, and to provide an expensive appearance to the decorative member.

A decorative member for outdoor use according to the first aspect of the present invention has an external surface that is exposed externally, and is adapted to be coupled to a main functional member. The decorative member includes an outer member and at least one inner member. The outer member is a metal member having inner and outer surfaces.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

Selected embodiments of the present invention will now be explained with reference to the drawings. It will be apparent to those skilled in the art from this disclosure that the following description of the embodiments of the present invention is provided for illustration only, and not for the purpose of limiting the invention as defined by the appended claims and their equivalents.

As shown in FIG. 1, a dual bearing reel in which an embodiment of the present invention is applied has a low profile-type reel to be used for bait casting. This dual bearing reel includes a reel unit 1, a handle assembly 2 that is disposed on one side of the reel unit 1 for rotating a spool 4, and the spool 4 for winding fishing line mounted rotatively and detachably within the reel unit 1. A star drag 3 for adjusting drag is provided on the same side of the reel unit 1 as the handle assembly 2.

The reel unit 1 has a frame 5, and a first side cover 6 a and a second side cover 6 b that are mounted to both sides of the frame 5.

The frame 5 is made of an aluminum alloy. The first side cover 6 a and the second side cover 6 b (examples of the outer member) have a first side plate 7 a and a second side plate 7 b that are respectively mounted thereto, and a plurality of connecting portions 8 that connect the first side plate 7 a and the second side plate 7 b. The first side plate 7 a and the second side plate 7 b are integrally formed with the connecting portions 8.

As shown in FIGS. 2 and 3, the first side cover 6 a and the second side cover 6 b are coupled to the first and second side plates 7 a and 7 b by threadedly coupling screw members 30 into a plurality of cylindrical portions 20 (examples of inner members and coupling members) from the inner sides of the first side plate 7 a and the second side plate 7 b. The cylindrical portions 20 are fixedly attached to the inner surfaces of the first side cover 6 a and the second side cover 6 b such that said cylindrical portions 20 and the first side cover 6 a, and the cylindrical portions 20 and the second side cover 6 b respectively are formed as one-piece unitary members. Accordingly, the first and second side covers 6 a and 6 b are coupled to the first and second side plates 7 b (examples of main functional members) via the cylindrical portions 20. Because of this, screw members 30 are not exposed on the surfaces of the first side cover 6 a and the second side cover 6 b. The first side cover 6 a and the second side cover 6 b are formed by press molding an aluminum alloy plate member.

The cylindrical portions 20 are made of a synthetic resin, and are bosses for installing/supporting the screw members 30. Concave portions 22 that are opened in the ends of the cylindrical portions 20 are formed by cutting and the like, and threaded portions are formed therein in order to mount the screw members 30. Although the cylindrical portions 20 are cylindrical members with threaded concave portion 22 formed thereon, the shapes of the cylindrical portion and the concave portion 22 are not limited to those described herein. The inner members of coupling members can have any shape as long as they can couple the outer member to the main functional member.

The cylindrical portions 20 are made of one synthetic resin selected from the group consisting of polyamide resins such as Nylon 6 or Nylon 66, polyphenylene sulfide (PPS) resins, polyethylene resins (PE), and polypropylene (PP) resins. The cylindrical portions 20 are attached to the first side cover 6 a and the second side cover 6 b by chemical bonding. Here, alumite 11 is formed on the aluminum alloy first side cover 6 a and second side cover 6 b (see FIG. 4). A fine triazine thiol powder is diffused on the inner surfaces of the first side cover 6 a and second side cover 6 b by an electro-deposition plating process to form an electro-deposition layer 12 (see FIG. 4), which will be described below. The cylindrical portions 20 are attached to the inner surface of the first side cover 6 a and the second side cover 6 b by inserting a portion of or the entire first side cover 6 a and second side cover 6 b into a die and outsert molding or insert molding the cylindrical portions 20 to the electro-deposition layer 12 on the portions of the cylindrical portions 20 that are inserted into the die.

More specifically, the cylindrical portions 20 are attached to the first side cover 6 a and the second side cover 6 b by performing an organic plating process using a special metal surface preparation agent RTD that chemically reacts with both a metal such as an aluminum alloy and a synthetic resin. Then, the RTD on the metal surface is directly attached to the synthetic resin within the die. Triazine thiol has a quality in which an R group therein will bond with a synthetic resin, and a sulfone group SH therein will bond with a metal. The fine triazine thiol powder is diffused by the electro-deposition plating process. Accordingly, the cylindrical portions 20 are firmly chemically bonded to the first side cover 6 a and the second side cover 6 b.

Each member (hereinafter generally referred to as component 10) that forms the reel unit 1 is made of an aluminum alloy, and an electro-deposition process is performed on the surfaces of the components 10. As shown in FIG. 4, alumite 11 is formed on the surface of the aluminum alloy components 10 by means of an alumite treatment. The electro-deposition layer 12 is formed on the surface of the alumite 11 by means of an electro-deposition process.

The alumite 11 is formed by anodizing the aluminum alloy. When the components 10 are made into anodes and subjected to electrolysis in a solution such as sulfuric acid, a film is formed thereon due to the oxygen that is generated by the anode.

The electro-deposition layer 12 is formed by diffusing fine triazine thiol powder by means of an electro-deposition plating process. When this type of electro-deposition is performed, the components 10 on which the alumite 11 has been formed are immersed into a coating tank, where the components 10 become cathodes and the electrode plate on which the coating layer is provided becomes an anode. In this manner, a coating is placed on the components 10 by applying a DC voltage thereto. Since formation of the alumite is well known in the art, further explanation is omitted herein.

In this dual bearing reel, the synthetic resin cylindrical portions 20 are fixedly attached to the inner surface of the first side cover 6 a and the second side cover 6 b. Here, because there are few limitations with respect to the metal first side cover 6 a and the second side cover 6 b, an expensive exterior appearance can be obtained without post-processing even if forging is employed. In addition, because the cylindrical portions 20 are fixedly attached to the interior surface of the first side cover 6 a and the second side cover 6 b, the attachment portions for installation/support are not exposed on the surface even if a press molded member is employed in the dual-bearing reel. Thus, cost increases are prevented, the exposure of the attachment portion on the surface is prevented, and an expensive exterior appearance can be obtained.

As shown in FIG. 8, grips 212 a, 212 b, and brake levers 213 a, 213 b are provided on both ends of the handle 204. In addition, a speed control device 215 that can display the speed at which the bicycle is traveling is mounted on a central portion of the handle 204.

The speed control device 215 is disposed in a box-shaped control case 227, and a display 224 is disposed on the upper surface of the control case 227. As shown in FIG. 9, the case 227 has an upper case 228 in which the display 224 (another example of main functional member) is disposed, and a lower case 229 (another example of outer member) that is disposed opposite the upper case 228. The upper case 228 and the lower case 229 are made of an aluminum alloy. Cylindrical portions 220, which are made of a synthetic resin and serve to support various substrates 225 (another example of inner members) of the display 224, are attached to the surface of the lower case 229 that faces the upper case 228. In other words, the lower case 229 supports the substrates 225 via the cylindrical portions 220. The method of attaching the cylindrical portions 220 and the lower case member 229 is identical to the aforementioned embodiment and is therefore omitted. With this speed control device 215, because cylindrical portions 220 that are made of synthetic resin are fixedly attached to the inner surface of the metal lower case member 229, cost increases are prevented, the exposure of the attachment portion on the surface is prevented, and an expensive exterior appearance can be obtained.

(b) In the previous embodiment, a fine triazine thiol powder was diffused by an electro-deposition plating process and then chemical bonding was performed. However, the attachment method is not limited thereto. The inner member may be attached to the outer member by any conventional adhesion methods. For instance, the inner may be attached to the outer member with epoxy-type, acryl-type, or urethane-type adhesives

However, as shown in FIG. 10, the cylindrical portions 20 may be linked to one another via a linking portion 40, such that the cylindrical portions 20 and the linking portion 40 form a one-piece unitary member. Still alternatively, there may be provided only one cylindrical portion. In addition, the cylindrical portions 20 are bosses for installing/supporting the screw members 30 in the aforementioned embodiments. However, the inner members may also be projections which do not have the concave portions.

Furthermore, although the inner members or the coupling members are embodied as the cylindrical portions in the aforementioned embodiments, the shape of the inner members is not limited thereby. The inner member or the coupling member may take any shape as long as the outer member or the side covers can be coupled to the main functional member or the side plates via the inner member or the coupling member.

According to the present invention, cost increases are prevented, the exposure of the attachment portions on the surface is prevented, and an expensive exterior appearance can be obtained because inner members made of synthetic resin are fixedly attached to the inner surface of a metal outer member.
